    Background The treatment landscape for multiple myeloma (MM) has undergone recent changes with the regulatory approval of several new therapies indicated for second- and later-line disease. Using data from Connect MM, the largest multisite, primarily community-based, prospective, observational registry of MM patients in the United States, selection of second-line treatments was evaluated during a 5-year period from 2010 to 2016. Patients and Methods Eligible patients were aged ≥ 18 years, had newly diagnosed MM ≤ 2 months before study entry, and were followed for up to 8 years. Patients who received ≥ 2 lines of therapy were analyzed. “Tepee” plots of stacked area graphs differentiated treatments by color to allow visualization of second-line treatment trends in MM patients. Results As of February 2017, 855 of 2897 treated patients had progressed to second-line treatment. Treatment selection was heterogeneous; shifting patterns of treatment choices coincided with the approval status of newer agents. The most common treatment regimens in the early part of the decade were lenalidomide and/or bortezomib, with or without dexamethasone, with increasing use of newer agents (carfilzomib, pomalidomide, daratumumab, and elotuzumab) and triplet combinations over time. The influence of the baseline patient characteristics of age, history of diabetes, peripheral neuropathy, and renal function on treatment choice was also examined. Conclusion These findings indicate that community physicians are current in their MM management practices, with uptake of new drugs and acquaintance with results of randomized clinical trials using combinations almost concurrent with their regulatory approval and publication.

    Treatment Outcomes and Health Care Resource Utilization in Patients With Newly Diagnosed Multiple Myeloma Receiving Lenalidomide-only Maintenance, Any Maintenance, or No Maintenance: Results from the Connect MM Registry
    (Elsevier, 2018-07-01) Rifkin, Robert M.; Jagannath, Sundar; Durie, Brian G. M.; Narang, Mohit; Terebelo, Howard R.; Gasparetto, Cristina J.; Toomey, Kathleen; Hardin, James W.; Wagner, Lynne; Parikh, Kejal; Abouzaid, Safiya; Srinivasan, Shankar; Kitali, Amani; Zafar, Faiza; Abonour, Rafat; Medicine, School of Medicine
    Purpose Maintenance therapy after autologous stem cell transplantation (ASCT) improves clinical outcomes in multiple myeloma (MM), but the effect of continued treatment with lenalidomide-only maintenance, or any maintenance, on health care resource utilization (HCRU) is largely unknown. Methods Here we present an analysis of HCRU and clinical outcomes in a cohort of patients from the Connect MM registry, the largest, ongoing, observational, prospective US registry of patients with symptomatic newly diagnosed MM. In this study, patients with newly diagnosed MM who completed induction and single ASCT without subsequent consolidation received lenalidomide-only maintenance (n = 180), any maintenance (n = 256), or no maintenance (n = 165). HCRU (hospitalization, surgery/procedures, and concurrent medications [growth factors, bisphosphonates, or neuropathic pain medication]) was assessed starting from 100 days post-ASCT for up to 2 years. Findings Although the rates of hospitalization per 100 person-years were similar across groups at the end of years 1 and 2, the median duration of hospitalization was numerically longer with no maintenance. The rates of use of growth factors, bisphosphonates, and neuropathic pain medication were generally similar in all 3 groups. The receipt of any maintenance was associated with significantly reduced use of neuropathic pain medications during year 1. Of note, lenalidomide-only maintenance was associated with significantly longer progression-free survival (54.5 vs 30.4 months; hazard ratio [HR] = 0.58; 95% CI, 0.43–0.79; P = 0.0005) and overall survival (OS) (median OS not reached in either group; HR = 0.45; 95% CI, 0.28–0.73; P = 0.001) compared with no maintenance. Likewise, the group treated with any maintenance had significantly longer median progression-free survival (44.7 vs 30.4 months; HR = 0.62; 95% CI, 0.47–0.82; P = 0.0008) and OS (median OS not reached in either group; HR = 0.50; 95% CI, 0.33–0.76; P = 0.001) than did the group that did not receive maintenance. Implications These findings suggest that in this largely community-based study population, post-ASCT maintenance therapy, including lenalidomide-only maintenance, improves clinical outcomes without negatively affecting HCRU.
